What's the difference between the climate in south and north of China?

First of all, the climate zone is different.

The south belongs to subtropical tropical monsoon climate, with high temperature and rainy summer and mild and dry winter.

Most of the north is temperate monsoon, temperate continental climate, high temperature in summer (decreasing humidity from coastal to inland), cold and dry in winter.

Second, the climate characteristics are different.

Climate characteristics of South China: high temperature and rainy in summer, cold and dry in winter, with the same period of rain and heat. There are four distinct seasons throughout the year and the weather is changeable. With the increase of latitude, the temperature amplitude in winter and summer increases correspondingly, while the precipitation decreases gradually.

Climatic characteristics of the north: Climatic characteristics: high temperature and rainy in summer, mild and little rain in winter, with rain and heat in the same period. It's not cold here in winter. The average temperature in 65438+ 10 is generally above 0℃, and it is hot in summer. The average temperature in July is generally around 25℃, and the direction of Xia Feng changes obviously in winter. The annual precipitation is generally above 1000 mm, mainly concentrated in summer and less in winter.

Qinling-Huaihe Line is the geographical dividing line between north and south of China. The north and south of this line are different in natural conditions, agricultural production methods, geographical characteristics and people's living customs.

Temperate monsoon climate is distributed in the area north of Qinling-Huaihe River, mainly including North China Plain, Loess Plateau and Northeast Plain. The subtropical monsoon climate is distributed in the south of Qinling-Huaihe River in China, including the middle and lower reaches of the Yangtze River, the southeast hills, the Sichuan Basin and the Yunnan-Guizhou Plateau.

North-south dividing line, traditional north-south dividing line, 1 month 0 degree isotherm, 800mm isoprecipitation line, paddy field and dry land distribution dividing line, rice and wheat planting dividing line,? The dividing line between subtropical zone and warm temperate zone, between subtropical evergreen broad-leaved forest and temperate deciduous broad-leaved forest, between humid and semi-humid, between subtropical monsoon climate and temperate monsoon climate.

Climatic characteristics of north and south

In most areas north of Qinhuai, rivers and lakes will freeze in winter. When winter comes and the north wind whistles, most trees will lose their leaves, and the leaves that do not lose their leaves are mostly needle-shaped, which is called conifers. Because the annual precipitation in the northern region is less, and the precipitation is mostly concentrated in summer, the river water volume is small and the water level changes greatly. The flood season is only formed in summer, the time is relatively short, and the river sediment concentration is relatively large.

In the south of Qinhuai, on the other hand, there is no ice in winter, no deciduous trees and evergreen seasons. The river has large water volume, small water level change, long flood season and small river sediment concentration.

Differences in agriculture and customs between North and South.

From the perspective of agricultural production and people's living customs, the difference between the north and the south of Qinhuai is more obvious. The cultivated land in the north is dry land, and the main crops are wheat and miscellaneous grains, which are harvested twice a year or thrice every two years; Paddy fields are the main crops in the south, and subtropical cash crops such as rice, sugarcane and tea are the main crops, which are harvested two or three times a year. People usually say that "northern wheat and southern rice, southern boats and northern horses" is a true portrayal of this difference.

Qinling-Huaihe line passes through Gansu, Shaanxi, Henan, Anhui, Jiangsu and other provinces, which is an important geographical dividing line in central and eastern China. There are significant differences in climate, rivers, vegetation, soil and agricultural production between the north and the south.

South China pays attention to the construction of river networks for water storage, soil and water conservation, and the protection of agriculture 100 days without rain, so the unit output of agriculture is high, industrial and agricultural production can be guaranteed, and the economy can develop sustainably.

There is no water supply in the north, which is prone to natural disasters, heavy rain and drought, which has caused instability to industrial and agricultural production and urban water supply.
